STATES PATENT OFFICE RUDOLF WILHELM, 0F ESSEN-ALTENESSEN, GERMANY, ASSIGNCR TO ARNOLD BEGKERS, OF GOLOGNE-KALK, GERMANY INSULATING MEANS FOR COKE-OVEN HEADS Application filed February 15, 1926, Serial No. 88,207/am1 in Germany February 25, 1925.

This invention relates to insulating means for coke oven heads, and has for its primary object to provide an insulating covering for the brick work of the oven head which will prevent the radiation of heat, the leakage of gases and air from the oven chambers or the entering of air thereto, and thus materially increase the operating efiiciency of the oven while also reducing the consumption of gas necessary to maintain the oven at the proper temperature.

It is another important object of the invention to provide such an insulating means for coke oven heads which will automatically accommodate itself to expansion and contraction of the brick work, thus avoiding the formation of cracks in the covering through which the heat and gases may escape.

With the above and other objects in view, the invention consists in the improved insulating means for coke oven heads, and in the form, construction and relative arrangement of the several parts as will be hereinafter more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings, wherein I have disclosed several simple and practical embodiments of my invention, and in which similar reference characters designate corresponding parts throughout the several views,-

Figure 1 is a horizontal sectional view through a coke oven head provided with one embodiment of my present improvements, and

Figure 2 is a similar view showing an alternative construction of the invention.

Referring in detail to the drawings, and more particularly to Fig. 1 thereof, the separating wall a between two coke oven chambers is of the usual brick work construction and in projecting relation to the face of this wall head the spaced cast iron frames 6 and c are arranged. These frames are of angular form and have inwardly projectingopposed flanges extending upon the face of the wall head as clearly shown in the drawings. To these flanges at the outer faces thereof the opposite side edges of an expansible and contractible metalplate cl are securely fixed by means of screws or other analogous fastening elements. The intermediate portion of this plate is provided with one or more corrugations 6 extending longitudinally there of. The space between the inner side of this plate and the face of the wall head is filled with ashes, sand or other insulating material indicated at f. Stayirons g and k are associated with each of the castings Z2 and c and extend forwardly therefrom but owing to the provision of the yieldable plate d, it is apparent that relative movement. of these stay irons or the castings will have no effect upon the efficiency of the packing or insulating material f. This material also serves the purpose of tightening the frame castings against the brick work of the wall head and with relation to each other.

- It will be seen that the plate d, while capable of yielding to variations in temperature, serves to effectively confine the insulating material against the face of the brick work which completely fills up any cracks, or crevices developing therein. Thus, there is obtained a complete insulating covering pre venting heat losses through radiation or leakage and which automatically accommodates itself to the expansion or contraction of .the wall head.

In Fig. 2 of the drawings I haveillustrated another form of the invention in which the face of the oven head may be first covered by a layer of insulating material, such as kieselguhr, asbestos or the like shown at b. This layer of insulating material is then confined and secured in place by a cast metal cover 0 which as shown, may be in one piece, or if desired may consist of two sections as shown in Fig. 1 of the drawing. In the illustrated constructions I have shown the oven cham- V bers is provided with suitable doors Z, said doors having associated therewith suitable packing means which automatically tighten the doors in place and prevents leakage.

. However, this feature constitutes no part of the present application, but is fully shown, described and claimed in a companion application filed of even dateherewith.

From the foregoing description considered in connection with the accompanying drawings, manner of application and several advantages of the embodiments of the invention herein disclosed will be clearly and fully understood. It will be seen that my new insulating means for coke oven wall heads in either form thereof is relatively simple in its construction, highly elficientfor the purpose in view and can be easily and quickly applied at nominal cost. While I have illustrated and described several practical examples of my present improvements, it is nevertheless, to be understood that the essential features thereof may also be embodied-in other alternative structures and I accordingly, reserve the privilege ofi adopting all such legitimate changes therein as may be fairly embodied within the spirit and scope of the appended claims.

1 A coke oven comprising two coke oven chambers having a separatin wall in common and each of said chambers having a lateral doorway at one lateral end of said wall, a metal cover for said end of said wall between the doorways, said cover including laterally inwardly extending members, a bridging plate, capable of yielding to variations in temperature, engaging said members, and a layer of insulating material associated with said bridging plate.

2. A coke oven comprising two coke oven chambers having a separating wall in common and each of said chambers having a lateral doorway at one lateral end of said wall, a cover for said end of said wall, said cover being trough shaped and comprising metal frames of angular form spaced from each other, a corrugated plate connecting the frames and bridging a space therebetween, and a layer of insulating material'between the plate and said end of said wall.

3. A coke oven comprising two coke oven chambers having a separating wall in common and each of said chambers, having a lateral doorway at one lateral end of said wall, a metal cover for said end of'said wall between the doorways, said cover. including complementary parts spaced from each other, and a bridging plate, capable of yielding to variations in temperature, engaging said parts and bridging a space between them.

4. A coke oven comprising two coke oven chambers, having a separating wall in common and each, of said chambers having a lateral doorway at one lateral end oi said;

wall, protective covering for said end of said wall between the doorways, said covering including separat'edparts with aspace be; tween them, a bridging plate, capable oi ylelding to variations in. temperature, engaging saidparts and" bridging a space between them, and insulating material disposed between said plate and said end ofj said' wall,

In testimony that I" claim the foregoing as,

myinvention, l have signed my namehereto.
